The object of my invention is to pro-' vide for an extension table atwo-part extension leaf whichmay be hidden Within the body of the tablebeneath the main leaves and so mounted that it may be automaticallyprojected into or from storage position by the simple application of alifting force to the outer end of one section of the leaf. Theaccompanying drawings illustrate my invention. I i

. Mounted upon the usual supportof the slide bar structure on oppositesides of the median line of the table are two U-shaped brackets 16 and17. Pivoted to the vertical arms of bracket 16' are the ends of a U-shaped leaf-lifting bar 18 and pivoted to the vertical arms of bracket17 are the ends of a U-shaped leaf-carrying bar 19, the tie 18 and 19being oppositely placed relative.

table when the extension leaf is in service,

position. Hinged to the inner end of extension leaf section 21,preferably by a concealed hinge such as hinge 22 is the inner end of thesecond extension leaf section 23. The upper ends of the vertical arms ofbracket 16 are formed at 16 into seats for the U-bar 19 and are sopositioned that when said U-bar is seated in the seat 16 and leaf .21isextended to service position said leaf section will be supported inthe table leaf plane resting upon the cross bar of U-bar 19 and upon oneof the slide bars 12.

Oneedge of the extension leaf 21-23 is provided with the usual dowels 24for entry into the usual pockets 25 in the inner edge of main leaf 10and the other edge of the extension leaf section 21-23 is provided withpockets 26 adapted to receive the dowels 27 carried by the inner edge ofleaf The side arms of the two lJ-bars 18 and 19 are connected by thelinks, 30, 30 which U-bar 19, through the links 30, swinging upwardly.The free end of extension leaf section 23 rests upon the cross arm ofU-bar l8 and as leaf section 21 is lifted and U-bar 19 swings upwardlysaid U-bar serves to lift 1 ll-bar 18 and thus raise the free end ofextension leaf section 23, as said leaf 23 is propelled toward theadjacent slide bar 12 so that said free end will clear the adjacentslide bar 12. The hinged end of extension leaf section 21swings towardthe median plane of the table, the hinged edge ofextension leaf section23 sliding upon bar 15 until the cross arm of U-bar 18 rests upon bar 15and the cross arm of LE-bar 19 rests upon the upper endsof the verticalarms of bracket 1.6, whereupon further downward movement of the free endof extension leaf section 21 will bring said leaf section down upon thead] acent slidebar 12 and extension i.

leaf section 23 will rest upon the opposite slide bar 12.

Thereupon main leaves 10 and 11 may be projected toward each other andinto en gagement with the extension leaf, the dowels and pockets matingso as to vertically interlock the two extension leaf sections with themain leaves of the table.

In order to store the extension leaf th main leaves 10 and 11 will beseparated, the free end of the extension leaf section 21 swung firstupwardly and then downwardly, pivoting on the cross arm of the U-bar 19,and the free end of extension leaf section 23 being lifted by iJ-bar 18and then lowered as its free end clears the adjacent slide bar 12. v

I claim as my invention: 7

1. An extension leaf structure for extension tables comprising a pair ofextension leaf sections hinged together at their adjacent ends, a leverpivotally associated with the under side of one of said leaf sectionsand pivotally supported on a table base, a second lever pivoted to saidtable base and cooperable with the other leaf section to lift the same,and, a connection between said two levers.

2. An extension leaf structure for extension tables comprising a pair ofextension leaf sections hinged together at their inner ends, a bracket,a U-bar having its cross element pivoted to the under side of one ofsaid leaf sections and its free ends pivoted to said bracket, a secondU-bar pivotally mounted at its free ends and having its cross elementdisposed beneath the other extension leaf section to form aslidingsupport therefor, and connecting links pivoted to the two U-barsintermediate the ends of said bars.

3pMounting hardware for an extension leaf forextension tables comprisinga supporting bracket, a U-bar pivoted on said supporting bracket andadapted to have its cross bar pivotally associated with an ex tentionleaf, a second bracket, a U-bar pivotally associated with said secondbracket and oppositely arranged relative to the first U-bar, the crossbar of said second U-bar being adapted to have a sliding engagement withthe under face of an extension leaf section, and a connection betweenthe side arms of said U-bars. 7

4. Mounting hardware for an extension leaf for extension tablescomprising a supporting bracket, a lever pivoted at its one end to saidbracket and provided adjacent its opposite end with means adapted toconnect said lever end pivotally to an extension leaf section, a secondbracket spaced from said first bracket in the direction of extenits one.end. to said. second bracket andpro jecting oppositely relative to saidfirst bar, the free end of said second lever being adapted for slidingengagement with a second extension leaf section, and a link pivoted tosaid levers intermediate the ends thereof.

5. An extension leaf structure for extension tables comprising a leverpivoted at its one end to a table. base, an extension leaf section,meanspivotally connecting'the free end of said lever to said sectionintermediate the ends thereof, a second extension leaf section havingits one end hinged to an end of said first leaf, a second lever pivotedat its one end to said table base and having its opposite end underlyingthe free end of said second section, and a link'pivoted to said leversintermediate the ends thereof. I

6. in combination, a table comprising a base, spaced parallel slide barsmounted on opposite sides of the longitudinal median ine of said table,a pair" of main leaves mounted on said slide barsand relatively movablelongitudinally of said base,- said slide bars forming; with said base,ade pressed pocket of a transverse dimension less than that of saidleaves, and an extension leaf unit permanently mounted in said pocketand comprising two extension leaf sections hingedly connected to eachother, a lever pivoted to one of said sections and to said-base wherebysaid sectionis swingable about an axis parallel to said median line, anda second lever pivoted to saidbase and engaging the other of saidsections whereby, when said first section is swung about its axis andinto the" plane of said main leaves, said second section'is alsoprojected into the plane ofsaid main leaves.

In witness whereof, I have hereunto set my hand at Wabash, Indiana, this15th day of March, A. D. one thousand nine hundred and thirty. v
